Data may influence my opinion.
The difference between the first place and the second place may be also
important for my opinion.

2 reasons:
1)I know that Deep Fritz has a tendency to play faster when it gets a big
advantage and I believe it is not a good descision.

I remember a game that was posted here(If I remember correctly by sune larson)
and in that game Deep Fritz lost when I found that it did a mistake because of
bad time management.

The game was based on the opening from the game insomniac-shredder in the last
ICC tournament.

I believe that the decision of Fritz to play faster when it has advantage is
a compromise of Fritz's programmers in order to make the customers more happy.

I can explain it.
I believe that Deep Fritz cannot earn more than 5 elo points from not playing
faster when it gets a clear advantage.

I believe that customers may become angry when they see a program calculates for
a long time in a clearly winning position.
It is not only for human-computer games but also for engine-engine games
because if engine-engine games takes more time the customers can see less games.

2)I know that Christophe worked on improving the time management of tiger and I
believe that he knows what he is doing and tiger is using time better than
most programs(I understood that tiger uses time in a different way than other
programs).

I remmeber that christhophe said that he is afraid that other operators are
going to change tiger's time management and he is 99% sure that the change is
going to be counter productive.
